Why did the poet choose stamps, ship tickets, cemeteries and the sea in different periods?

Because nostalgia is very abstract, these specific images in different periods can better show what nostalgia is like in different periods, which is more helpful in understanding nostalgia in a specific period.

Four unrelated items such as stamps, ship tickets, tombs, and straits, under the maintenance of nostalgia, have a specific emotion that is chanted repeatedly to produce different artistic effects.

When he was a child, the author went to boarding school and corresponded with his mother. After getting married, I went to the United States to study, and then took a boat back to Taiwan, using the boat ticket to express my homesickness.

Later, my mother passed away, and I did not lose my mother's love, so I used the grave to express my nostalgia. Due to political reasons, the strait separated the mainland and Taiwan for a period of time, and the strait was used to express more Big homesickness.

Appreciation of "Nostalgia":

After reading this poem, readers will see four vivid and specific pictures of life: Part One: Learning in childhood, separation of mother and son, sending letters of comfort; Part 2:

When you become an adult, you say goodbye to your new wife, leave your hometown, and stay away from your family. Section 3: Separated, mother and child are not allowed to see each other; compatriots rarely get together, and the country cannot be unified.

“A vertical sense of history, a horizontal sense of position. A sense of reality crossing at a crossroads.” It integrates pure beauty and richness, and the image of the object is concentrated and vivid, such as stamps, coupons, etc. solemn and without details. The book has branches, profound artistic conception, rich and implicit content, and readers can deeply feel the author's rich and strong emotions.

The poet's homesickness is not expressed directly, but through association and imagination, four images of the art of life are shaped and presented to readers with their long connotations.

The poem goes back and forth, with singing and sighing melodies. In the same place, there are repetitions, that is, I am at this end..., there are repeated words: small, narrow, short and shallow; there are changed quantifiers: Mei, Zhang, Fang, Wan.

The author uses these artistic methods to enhance the charm of the poem. This is a tender and sad "song of memories" and a love song for overseas students. It's true to its word, has endless meaning, and the taste is really hard to fathom.
